IImageDecoder::BeginDecode (Windows Embedded CE 6.0)

1/6/2010

This method is used to start decoding the currently selected frame.

Syntax

HRESULT BeginDecode(
  IImageSink*                   sink,
  OPTIONAL IPropertySetStorage* newPropSet
);

Parameters

• sink
  [in] A pointer to an IImageSink interface that receives the image data that results from decoding the frame.

• newPropSet
  [in] An optional pointer to an IPropertySetStorage interface that contains a property set. The decoder should attach this set to the decoded image when it calls IImageSink::PushPropertyItems, rather than the property set it derives from the decoded image.

Return Value

If successful, this method returns S_OK.

If it fails, this method should return one of the following error values:

• E_NOTIMPL
• E_POINTER
• E_UNEXPECTED
